目的 减少后颅窝肿瘤 (髓母细胞瘤 )手术出血 ,减少手术中的输血。方法 对比两个年度 (1994～ 1995年度和 1997～ 1998年度 )的髓母细胞瘤手术中的输血量 ,改后颅窝咬骨窗术为开骨瓣术 ,在显微镜下切除肿瘤。结果 在病儿年龄、肿瘤大小无差异的条件下 ,手术中的平均输血量1994～ 1995年度 (32 5 7ml)明显多于 1997～ 1998年度 (144 2ml) ,未输血率 1994～ 1995年度 (6 % ,2 /35 )明显低于 1997～ 1998年度 (40 % ,15 /38)。结论 精细手术操作和在显微镜下切除肿瘤是减少手术出血的关键。
Objective To reduce surgical bleeding in posterior fossa tumors (medulloblastoma) and reduce transfusions during surgery. Methods The volume of blood transfusions in patients with medulloblastoma during two years (1994-1995 and 1997-1998) was compared. The craniotomy was performed with bony osteotomy and the tumors were removed under the microscope. Results In the age of sick children and no difference in tumor size, the average blood transfusion during operation was significantly higher than that of 1997-2994 (144 2ml) in 1994-1995 (1994-295) %, 2/35) was significantly lower than that of 1997-1998 (40%, 15/38). Conclusions Fine surgical procedures and resection of the tumor under the microscope are the keys to reducing the risk of surgical bleeding.
